How much??

[Parksy2000]

Hiya
My 10 week old was prescribed Ranitidine for silent reflux. The doc said 3 times a day at 0.6ml. I'm not sure how he's worked this out, any ideas?

My baby weighs 12lb - 5.5kg. I would of worked this out by 5.5 x 3 / 150 x 10 = 1.1ml 3 times a day. The solution is 150mg in 10ml.

I know they can have up to 3mg per kg so even if he had 2mg per kg the dosage would be 0.7mls per day?

Any help on this would be greatly received. I've been to the GP three times now to check dosage, first time she said oh it's too hard to work out so just give him 1ml twice a day, I wasn't happy with this so saw another GP who said yep that's right, you can't have 0. of a ml cos it's too small which is rubbish! 3rd GP then said oh he should be having it 3 times a day and his dosage would be 0.6ml! I mean, what the hell is going on here? Seams like no one has a clue!!

Anyway, thanks for reading

0.7ml - 3 times a day

The numbers all work if you take your childs weight at 5kg.
I suspect they are going to the nearest kg (and underestimating the weight to take account of variability and so as not to over dose)

BUT thats looking at the numbers, and I don't know Ratanidine doses, so I'm taking your numbers.

Surely better to start low and build up to max dose if needed, so yu find the minimal effective dose for your child?

Exactly. Just because they can have up to 3mg/kg doesn't mean they need to have or should have the full dose.

Is it not the Pharmacist's job to check that the dose is not harmful? I don't know.

But since the dose is within the parameters for being ok I'm not quite sure what the problem is.

Thanks, he was on minimum dose but it wasn't working which was why I got it checked out.

If Lo has reflux, or suspected reflux, its worth getting them checked for tongue tie as the symptoms can be similar.
